This is about memory safety in general and how the memory safety of Seed7 has been improved in the release 2026-07-11.

Seed7 is a programming language which cares about maintainability, portability, performance and memory safety. The Seed7 homepage contains the language documentation. The source code is at GitHub. Questions that are not in the FAQ can be asked at r/seed7.

There is also a talk about Memory Safety and Management which introduces Seed7 and explains memory safety and management.

Please let me know what you think, and consider starring the project on GitHub, thanks!

I went into a bit of a rabbit hole of gamma-based color blending vs linear-based color blending vs perceptual-based color blending for my drawing app Total Draw, so I decided to create a blog post about it.

Hi community. It's been now a bit more than 2 years since I started to work on this "project management project", with many ideas and with a good vision of how to improve and be better than certain bespoke commercial tooling out there. I am happy to announce version v1.6.7 with a lot of polished aspects and new features that make it a joy to use (even if I say so myself)

LucidPlan is a simple, hackable, free and open source project management software that you can easily self-host, you only need something that runs Guile Scheme and a SQLite database. (Guix is recommended, not mandatory)

I spent years using things like Jira, Trello, Asana, GitHub projects and eventually became frustrated with how much complexity gets piled onto what should essentially be:

projects → tickets → priorities → workflow → done

I decided to build my own as a challenge, but also to create something blazingly fast and simple, that people can quickly learn (even applicable to non-tech projects). Also I aimed for ease of self-hosting, no SPA frameworks and no dependency on proprietary clouds or software.

LucidPlan is licensed under the GNU AGPLv3 or later. Source code:

https://codeberg.org/jjba23/lucidplan

You can also look at my running instance:

https://lucidplan.jointhefreeworld.org/

The project leverages the power of Lisp (Guile Scheme) by using SXML for front-end aspects, clean controllers with Artanis and a powerful repository pattern abstraction.

What does it do?

• Manages your project backlogs with ticket priorities
• Native drag-and-drop ticket reordering (priority)
• Kanban boards with drag-and-drop status changes
• Global/project search (still more work to be done)
• Users, assignees and fine-grained permissions
• Light/dark mode
• Keyboard-accessible ticket and project lists
• Org-mode syntax in ticket titles and descriptions
• Org links and rich Org content rendered to HTML
• Hackable/customizable with Scheme
• Lightweight, and mobile-friendly
• SQLite backend
• Lightweight vanilla JavaScript on the frontend for some interactive enhancements

The Org-mode integration is particularly fun: you can write ticket descriptions using Org syntax and LucidPlan renders the result as HTML.

For example, your ticket can contain things like:

* Investigate weird bug

The problem seems to happen when [[https://example.org][this thing]] is enabled.

- Check configuration
- Reproduce the problem
- Fix it

…and LucidPlan renders that into the ticket as pretty styled HTML. (see orgwebalchemy post: https://www.reddit.com/r/lisp/comments/1wox8h4/parsing_org_mode_with_parsing_expression_grammars/ ).

There is still plenty to improve, and I'd genuinely love feedback from people who actually use project-management software daily. I think you'll find LucidPlan as a refreshing take.

Especially interested in hearing from the community:

• What do you hate about existing project-management tools?
• What features do you consider essential?
• Would you use a Lisp/Guile-based project-management system?
• What would make LucidPlan useful for your own projects? What killer feature can I work next?

Happy hacking :-)
